THOMAS CUONAN, 0F CHAMPLAIN, NEW YORK AUTOMATIC} FAUCET.

a lication filed June 21, 1916. Serial No. mess.

citizen of the United States, and a resident of Champlain, in the county of Clinton and State of New York. have invented a new and improved Automatic Faucet, of which the following isa full, cl 111', and exact description.

My invention relates to automatic faucets. An object is to provide a self-closing faucet for dispensing vessels, such, for example, as eoll'ee urns, water coolers and the like, the valve being operable by the pressure of a tumbler, eup or other receptacle. held in position to receive the. liquid to be discharged from the faucet. Another object of the invention is to provide an automatic faucet so arranged that no packing is required for the portion of the valve projecting out of the faucet body. A'sti-ll further object of the invention is to provide the automatic valve with auxiliary llltlllS for maintaining the valve oli' its seat when desiring to drain the container.

lVith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1. is a side elevation of a faucet cmlmdying my invention;

Fig. 2 is a longitudinal section through the faucet: and

Fig. 3 is a cross section on line 3-3, Fig. 2.

Referring to the drawings, at is the faucet which has an enlarged part 5 provided with a separating wall (3 in which the valve seat 7 is formed. The valve 8 has a stem 9 which passes through a tubular projection 10 rising from the body of the faucet to the valve seat 7. The valve 8 has also a sleeve 11 concentric with the stem fitting on the tubular projection 10. The engagement of the sleeve with the projection, and that of the tubular projection with the stem, prevents liquid tlo\ving through the valve opening from leaking between the stem and the tubular projection 10.

The end of the stem projecting out of the faucet body "arries a coil spring 12 one end of which bears against the body of the faucet and the other end of which bears on a nut 13 threaded on the stem. The portion of the stem below the nut 13 passes through a slot 11 in an operating lever 15, the lever being fulcrumed on a cam 16, which cam is pivoted to an extension 17 of said extension lying between the stem and the delivery end 21 of the faucet. The extension passes through an opening 18 in the lever 15. The lever 15 has a. lip 19 at the opening 18 bearing on the extension 17 under the action of the spring 12.

The portion 20 of the lever between the extension and the delivery end 21 is bent to be easily engaged by the side of a tumbler, cup or other receptacle brought to the delivery end 21 of the faucet. Pressure applied by the tumbler or cup or other vessel on to the lever 20 will force the other end of the lever against the nut 13, raising the valve 8 from its seat (see dotted position of the lever and valve in Fig. 1), and alloWinga flow of liquid to the delivery end 21 of the faucet. The disengagement of the cup, tumbler or other vessel from the end of the lever 20 allows the spring 12 to seat the valve and cut off the supply of liquid to the delivery end. To prevent longitudinal displacement of the lever, the elongated opening 14 thereof is engaged by projections 22 of a Washer the. faucet,

23 mounted on the stem and retained thereupon by a threaded cap 2 1.

\Vhen it is desired to raise the valve 8 from its seat and retain it in that position, the cam 16 is moved through the medium of its extension 25 to the position shown in dotted line in Fig. 2, bninging the highest point 26 of the cam into engagement with the lever 15, causing the lever to rise on the ex-.

tension 17. The contact of the lip 19 with the extension causes the lever 15 to move bodily (see the dotted position of thelever. in Fig. 2), whereby the valve 8 is raised from its seat and maintained in that position until the cam 16 is lowered to the position shown in full line in Fig. 2.

1. In a faucet of the class described, a faucet body having a valve seat, a valve engaging the seat and having a stem passing through the body of the faucet, an oper ating lever engaging the valve stem and shaped to be engaged by a vessel brought under the faucet, a cam on Which the lever is fulcrumed, and a spring for maintaining the
